- Available Boundary Conditions for Analyses
  A comparison chart showing the available boundary conditions for each analysis type.
- Constraints
- Pressure
- Force/Displacement
  Apply uniform loads and/or displacements to faces, edges, vertices, or spots.
- Gravity Load
  Simulate the force of gravity as it affects your model.
- Translational Inertia Load
  Apply a uniformly distributed translational inertia load over the volumes of the parts in an assembly.
- Rotational Inertia Load
  Apply a uniformly distributed rotational inertia load over the volumes of the parts in an assembly.
- Inertia Relief
  Simulate deformations and stresses in cases where you have an unconstrained structure to which an active load is suddenly applied.
- Remote Load
  Apply distributed loads (tractions) to faces, general virtual connector, or spots that are statistically equivalent to a load applied on a single point.
- Remote Displacement
  Apply displacements to faces and/or spots that are statistically equivalent to a load applied on a single point.
- Thermal Load
  Simulate deformations and stresses induced by the temperature changes in your model.
- Bearing Load
  Apply a varying pressure load to full or partial face(s) of revolution.
- Distributed Mass
